Scenery highlights: geological and natural features of the forest
Black Hills National Forest packs a lot of scenery into a compact range: a 7,244 foot granite summit, a limestone canyon a thousand feet deep, mountain reservoirs, and pine country that runs farther than most people can cover in a summer. This is a look at the natural features worth planning around, all of it on forest ground, with how to reach each one.
Seen from out on the plains, the dense ponderosa pine forests look nearly black, which is where the Lakota name Paha Sapa, hills that are black, comes from. Up close the island in the plains turns out to be green, and it holds more variety than its size suggests.
The hills rose about 70 million years ago when a dome of rock pushed up through the plains. Erosion stripped the softer layers off the top and left an ancient core of granite and metamorphic rock, ringed by younger limestone and sandstone. That is why you can stand on bare granite in the central hills and walk a limestone canyon in the north on the same trip. Elevation runs from about 3,000 feet at the edges to 7,244 feet at Black Elk Peak, so the forest holds prairie grass, pine stands, aspen groves, and cold creeks within a short drive of each other.
